-ErrorAction Stop not work in Copy-Item

Question

Simple script:

"test" | Out-File "C:\existing_file.txt"
$ErrorActionPreference = "Continue"
Copy-Item "C:\existing_file.txt" "C:\NonExistingDir\file.txt" -ErrorAction Stop
"hello" | Out-Host

I have this output:

Copy-Item : Could not find a part of the path "C:\NonExistingDir\file.txt".
C:\Users\ESavin\AppData\Local\Temp\d3d410e0-79b3-4736-b7e7-5aba1ab11a12.ps1:1 знак:10
+ Copy-Item <<<<  "C:\existing_file.txt" "C:\NonExistingDir\file.txt" -ErrorAction Stop
    + CategoryInfo          : NotSpecified: (:) [Copy-Item], DirectoryNotFoundException
    + FullyQualifiedErrorId : System.IO.DirectoryNotFoundException,Microsoft.PowerShell.Commands.CopyItemCommand

hello

Why I get "hello" in output ?? -ErrorAction Stop not work??

update:

this code:

"test" | Out-File "C:\existing_file.txt"
$ErrorActionPreference = "Stop"
Copy-Item "C:\existing_file.txt" "C:\NonExistingDir\file.txt"
"hello" | Out-Host

worked as expected. there isn't "hello" in output.

Copy-Item ignore -ErrorAction and use only $ErrorActionPreference ??

As indicated by the help the ErrorAction parameter has no effect on terminating errors, which yours is.

    The ErrorAction parameter has no effect on terminating errors (such as
    missing data, parameters that are not valid, or insufficient 
    permissions) that prevent a command from completing successfully.
